GEORGE S. BLAKESLEE, OF CHICAGO, ILLINOIS.

DRIVING nncnfanrsm.

To all whom it may concern Be it known that I, Gnonen S. Bnannsnnn,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Driving Mechanism, of which the following is a specification, reference being had to the accompanying drawm s. T /Iyinvention relates to culinary appliances such as machines for mashing and creaming potatoes and performing other analogous culinary operations.

It has for its object to provide certain improvements therein, and more particularly in the driving mechanism by which the mashing and creaming devices are actuated. I accomplish this object as illustrated in the drawings and as hereinafter described.

What I regard as new is set forth in the claims.

In the accompanying drawings, Figure 1 is an elevation of my improved machine; Fig. 2 is an enlarged view, being a partial vertical section of the driving devices; Fig. 3 is a detail, being a cross-section on line 33 of Fig. 2; Fig. 4 is a plan view; and Fig. 5 is an enlarged detail, being a vertical section on line 5 5 of Fig. 1.

Referring to the drawings, 6 indicates a receptacle for the potatoes or other articles, which is in the form of a can having a removable cover 7. The receptacle 6 is mounted on legs 8 of any suitable character.

9 indicates a table placed under the receptacle 6 and supported by the legs 8, said table forming a support for an electric motor 10 which supplies power to the heating apparatus.

11 indicates a standard provided at one side of the apparatus and extending over the receptacle 6, as best shown in Fig. 2. Said standard is provided with a horizontal bearing 12 on which is mounted a shaft 13 on the outer end of which is a pulley 14 adapted to be connected by a belt 15 with a pulley on the armature shaft 16 of the motor 10, as shown in Fig. 1. By this means the shaft 13 is driven from the motor.

17 indicates a beveled pinion mounted on the inner end of the drive-shaft l3 and meshing with a gear 18 which is mounted on a vertical spindle 19, as best shown in Fig. 2. The spindle 19 is movable longitudinally through the gear 18, being connected thereto by a feather so that it rotates therewith Specification of Letters Patent.

notwithstanding its longitudinal movement therethrough. The gear 18 is provided with a journal 20 fitted in a suitable bearing 21 the horizontal portion 22 of the standard 23 indicates a bushing mounted in the horizontal portion 24.- of the standard 11 and forming a hearing for the spindle 19. As best shown in Figs. 2 and 1, the spindle 19 is in line with the center of the receptacle 6, and it is provided at its lower end with a head 25 having a squared socket to receive the upper end of a beater-shaft 26 adapted to operate in the receptacle 6, as shown in Fig. 2. The head 25 is not fixedly secured on the spindle 19, but isearranged to swing through an arc of about sixty degrees, so that it may be partially rotated independently of the spindle. To secure this action, the head 25 is connected with the spindle by a pin 27 which passes through the lower end of the spindle and has its ends fitted in seg mental slots 28 in the head, as shown in Fig. 3. The purpose of this arrangement is to permit the head 25 to be rotated slightly in order to adapt it to register properly with the squared upper end of the beater-shaft 26. By raising the spindle 19, obviously the head 25 may be disengaged from the spindle 26, thereby permitting the cover 7 to be re moved when it is desired to obtain access to the interior of the receptacle 6.

The spindle 19 is connected at its upper end to an arm 29 pivoted at 30 upon an upward extension 31 of the standard 11 so as to swing in a vertical plane. The connection of the spindle 19 with the arm 29 is secured by links 32 pivoted at their upper ends to the arm 29, as shown at 33 in Fig. 2, and pivotally connected at their lower ends to a collar 34 which is fitted upon a sleeve 35, said sleeve being fitted upon the upper end of the spindle 19 and connected thereto by a pin 36. A nut 37 screwed upon the lower end of the sleeve 35 holds the collar 84 in position. I thus provide a universal joint or connection between the arm 29 and the spindle 19. For the purpose of rocking the pivot 30 to move the arm 29 up or down, I provide a crank 38 which is secured to the pivot 30. The arm. 29 may be locked in its raised position, when desired, by means of a pivoted latch comprising an upwardly-extending arm 39 pivoted at 410 upon the extension 31 of the spindle, as shown in Fig. 2, and having a notch 41 adapted to receive the arm 29 in the manner shown in Fig. 5.

venience in 0 erating it. When it is desired to lockt e arm29 up to holdthe head- I spindle is slidably and rotatably mounted,

out of engagement with the beater-shaft, the latch 39 is swung over into positionto intercept said arm in the manner shown in Fig. 5, thereby securely looking it in its uppermost position It will be apparent that when the head- 25 is in engagement with the beater-shaft 26 such shaft may be rotated when the drive-shaft 13 is driven.

' hen it is desired to introduce or remove the materials from the receptacle 6, the crank 38 is operated to-lift the arm:29, car'- rying the spindle 19 upward tothe limit of its movement in that direction and releasing the beater-shaft so that the cover-plate may readily be removed. Preferably the coverplate is secured in position by providing it with straps 43 which fit" over lugs carried by the standard ll, as-shown inFig. 2, but

' any other suitable means of attachment'may be employed.

45 indicates areceptacleat the upper end vof the head 25 for intercepting and retain- ,ing oil that may run down the spindle 19.

That which" I claim as my invention, and

.desire tosecure by Letters Patent, is

1. In a driving mechanism a verticallymovable spindle, a bearing in which said means for rotating said spindle, a rocking lever rotatably connected with the upper end portion of said spindle for moving the same vertically, and means for locking said spindle in its elevated osition.

2 In a driving mec anism a verticallymovable spindle, a suitable support in which said spindle is journaled, mechanism carried by said support for rotatingsaid spindle a lever: mounted on said support, a link rotatably connected with said spindle and pivotally connected with said rocking lever whereby said spindle may be moved vertically by operating said'lever, and means for locking said spindle in'its elevated position.
